I am trying to install zaptel and libri in Ubuntu. As I've understood asterisk needs these files if I want to configure a conference call over sip.
I've downloaded zaptel and after make command I have the following errors:
/usr/src/zaptel-1.4.12.1/kernel/pciradio.c: In function ‘pciradio_start_dma’:
/usr/src/zaptel-1.4.12.1/kernel/pciradio.c:1701: error: implicit declaration of function ‘set_current_state’

Need help. Appreciate
This question is probably better on serverfault (and I can't seem to comment on Andrea's answer) but you might be better off using app_confbridge in Asterisk 10, if in your distribution. Then you will not need DAHDI (formerly Zaptel) installed at all to run a conference call.
